Dropped Calls with Iphone 4s
Hello,
I've a IPhone 4s and I'm facing real problems to do a call. At the moment I'v e really most times dropped calls. I didn't get until now a idea why and how and also I didn't see until know a structure behind this failure. But it haappens not always and I think it have to do something with the signal coverage.
I'm living in Abu Dhabi, UAE, and my carrier is Etisalat.
iPhone 4S, iOS 5.1
